Rezumat:

The organic solvent-waste samples were counted in a 2100 TRI-CARB Packard model liquid scintillation analyzer using the „Ultima Gold F scintillation liquid” cocktail. Nine large sample/cocktail plastic vials were prepared. A homogeneous emulsion sample-cocktail was obtained by heating the nine vials on water-bath at 50 0C. Six sets of measurements were performed. The compensation procedure of the direct values with unequal measurement precisions was used to calculate the activity and its deviation.
